  • Publication number: 20220312154
    Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

  • Publication number: 20220303882
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for operating a user equipment (UE) in a next generation (NG) radio access network (RAN) (NG-RAN) to validate a system information block (SIB) for non-public networks (NPNs). In one aspect, a UE receiving a SIB-one (SIB1) from a cell of the NG-RAN may determine whether the cell supports non-public networks (NPNs) based on the received SIB1. If so case, the UE may determine whether an NPN-identifier (NPN-ID) in the received SIB1 matches an NPN-ID of a SIB stored in memory. If so, the UE may validate the stored SIB based at least in part on the received SIB1. If not, the UE may invalidate the stored SIB and obtain a new SIB per standard procedures.

  • Patent number: 11438922
    Abstract: Aspects for MAC-CE duplication for packet repetition in uplink and downlink are disclosed. In one particular aspect a method of wireless communication includes receiving, by a user equipment (UE), a message including a component carrier (CC) identifier (ID) for a particular Medium Access Control (MAC) control element (MAC-CE). The method also includes receiving, by the UE, a first MAC-CE via a first CC of a plurality of CCs, and receiving, by the UE, a second MAC-CE via a second CC of the plurality of CCs. The CC ID included in the message corresponds to a CC ID for the second MAC-CE. The method further includes combining, by the UE based on the CC ID for the second MAC-CE, a first signal corresponding to the first MAC-CE and a second signal corresponding to the second MAC-CE to generate a combined signal for decoding.

  • Publication number: 20220183046
    Abstract: Certain aspects of the present disclosure provide techniques for sending a configuration for conditional configured grant (CG) occasions for uplink transmission to a user equipment (UE). Each conditional CG occasion may be associated with multiple conditional CG resources. Each conditional CG resource may be associated with a sending window. The UE may monitor within sensing windows for conditional CG resources of a certain conditional CG occasion for over the air (OTA) signals from other UEs to determine if the conditional CG resources are available for uplink transmission. The UE may skip the conditional CG occasion when the conditional CG resources are not available. The UE may perform uplink transmission on the conditional CG resources when the conditional CG resources are available.

  • Patent number: 11357013
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a set of frequency resources and a semi-persistent resource allocation indicating a semi-persistent resource occasion on each frequency resource of the set. The UE may monitor semi-persistent resource occasions on each of the set of frequency resources for a copy of a data transmission. If the UE receives and decodes the data transmission from at least one of the semi-persistent resource occasions, the UE may transmit an acknowledgement message on a frequency resource of the set. Additionally, the UE may refrain from transmitting a feedback message on the other frequency resources of the set. If the UE does not receive and successfully decode the data transmission from any of the semi-persistent resource occasions, the UE may transmit a negative acknowledgement message on one of the set of frequency resources.
